The cage (terrarium) is a 20 gallon fish tank which is fully automated with regards to having three different heating/lighting systems. The lid was custom made to significantly reduce operating cost by heating the terrarium not the room. It also allows you to control the heat within two degrees and retain moisture. Screens over the heating sources make it safe for the inhabitant. I was surprised when I added up the cost of the investment in the tank setup which was over $325. The three-way heat supply ensures backup in case there is an interruption in one of the sources
1. An adjustable heat lamp

3. A heating pad
4. and all the tank accessories
5. including timers
